Application October 16, 1952,

Serial No. 315,030

1 Claim. (01. 56-249) ment at each end of the lawn mower.

It is another object of the invention to provide a ground roller hanger or mounting which is adjustment, that is to say, in parallelism with the plane of the cutting elements.

With the foregoing and other objects in view, the invention has certain salient features of construction which will become manifest as the description proceeds taken in connection with the accompanying drawing wherein:

Figure 1 is a fragmentary perspective view of tion therewith.

Figure 2 is an elevational view showing the inner face of one of the roller hangers, and

Figure 3 is a rear elevational view of a conventional lawn mower on which the invention is shown.

Continuing with a more detailed description of the drawing, reference numeral l0 denotes a wardly of and in i2 of lawn mower.

The invention consists of a pair of opposed mounting plates I4. Each of these plates has a pair of elongated apertures or slots I 5 which are adapted to register with and receive the bolts I3 01 the lawn mower frame I 0. Nuts 46 are threaded onto the bolts l3 tosecure the mounting plate l4 firmly in position. Each plate I4 is further provided with an extension I1 on its lower edge, a portion of which is slitted and turned upon itself to form a hook I 8, the purpose of which will be presently described.

an arcuate The hanger arm 25 is interposed between the end of the slot 24 permitted by the plate l4, 2'! of the pin In order to yieldingly hold the arm 25 in a position so that the pin 26 will engage in a selected one of the recesses 28, the spring 22 within the box I 9 normally biases the arm towards the pin 26. When the desired adjustment of the arm 25 has been attained, the wing nut 2| is same against oscillative or ment.

Aifixed to or formed on the lower end of the arm 25 is a bearing 29 in which is journaled an end of the shaft 30 of the ground roller 3|.

It is evident from the foregoing that when it ground, it is necessary only to back out the screws 20 of the hangers at each end of the roller 3!. This will release the hanger arms 25 for oscillative displacement. To raise the cutting elements, the pins 26 are moved to recesses 28 in higher positions in the arms 25 whereupon the screws 29 are again positioned against the arms 25 to prevent their movement from adjusted positions. Conversely, the cutting elements are lowered by correspondingly lowering the pins 26 in relation to the arms 25.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claim is also considered to be within the spirit and intent of the invention.

What is claimed is:

In a lawn mower attachment, a ground roller mountingcoinprising apair of complementary hangers, said hangers each comprising a mounting plate having horizontal, vertically spaced bolt receiving slots for the attachment of said plate to the frame of a lawn mower, a slotted boss affixed to said mounting plate having a threaded bore and a counterbore, a"heade'd pin secured to one face of said mounting plate ad jacent its top, an arcuate hanger arm having its outer edge slidable in the and provided in its inner edge with relatively slot of s'aidboss 20 said coil spring for securing said'arm against movement in said boss.
